There is a bug setting the percentage width for a table within the Kendo editor.
1. Go to https://demos.telerik.com/kendo-ui/editor/index
2. Under Editor / Basic usage select the Table Wizard Icon and click Table Wizard to bring up the Wizard Dialog
3. You will notice that within this dialog the unit options for width and height are only px and em
4. Within this dialog create a table two columns and four rows
5. Place your cursor in one of the table cells again and click the Table Wizard button again to edit the propertied of the new table
6. The unit options for width and height are still only px and em. Go ahead and enter 100px into the width field and click Ok on the dialog
7. Once again with you cursor in one of the table cells, click the Table Wizard button again. Now the units options for all widths and heights for tables and cells are px, em and importantly %
8. If I now create a new table via the Table Wizard the unit options available are px, em and % as expected
I logged a previous, different bug about the Table Wizard in github here: https://github.com/telerik/kendo-ui-core/issues/4390 but have had no response, so is this the correct place for bug reports, or github?
